v ELECTRIC LAMP ManuellD'liaa Fernndez, Habana, Cuba u Application-November 20, 1937, Serial No. 175,624 i In Cuba January 14, 1937 l `a claims. '(01. 24o- 1112) p This invention relates to lamps and particularly to an improved electric lamp; an object being to rprovide 1 a construction y which will-v giver the desired llight and which/may be mounted-on a :A standor connected with any desired piece of furnjture H i Another object of the-invention Lis to providev an electric vlampe-having asuitableV supporting frame which will protect the bulb, and formed 1.0' to cause the light to shine inthe ldesired direction.

A further object,v more specifically, is to provide an electric lamp using a tubular bulb and provided with a reflector which may be rotated around the bulb so as to cause the light to shine in any desired direction.

In the accompanying drawings- Figure 1 is a perspective view of a frame constructed in accordance with the present invention;

Figure 2 is a longitudinal vertical sectional view through a complete lamp disclosing an embodiment of the invention;

Figure 3 is a transverse sectional view through Figure 2 approximately on the line 3--3;

Figure 4 is a perspective view with certain parts broken away and illustrating one of the rings shown in Figures 1 and 2;

Figure 5 is aperspective View of a second ringl embodying certain features of the invention;

Figure 6 is a perspective view of the reflector or shade shown in Figure 2;

Figure 'l is a perspective Vview of the protecting ring shown in Figure 2; and

Figure 8 is a perspective view of a ring embodying certain features of the invention.

Referring to the accompanying drawings by numerals, I indicates a frame which is formed with a plurality of tubes 2 connected with the respective rings 3 and 4. This frame is supplied with a number of identically shaped rings 5, as

shown in Figure 2, said rings being mounted on top of ring 3 and clamped in place by any desired y number of threaded rods 6. The top plate 1 may be solid throughout or formed into a ring as preferred. Preferably this plate or ring is solid throughout so as to receive a threaded member 8 whereby the lamp may be connected to a bracket or piece of furniture. The upper ends of the rods 6 are covered with ornamental caps 9, while the lower ends are threaded into the respective tubes 2 so as to clamp the plate 1, ring 5 and ring 3 together `and tothese tubes.

It will be noted that the ring 3 is provided with an annular rabbet or groove II) which coacts with the upstanding flange of a ring I I carried by the supporting ring I2vof the shade or reflector I3. The lower ring4 is clamped to the variousy tubes 2 by a plurality of threaded rods I4, which rodsat their lowerends carry the respective rings I5, I6, I1 and I8. The member I8 while functioning as a ring also functions as ay bottom for the lamp as this ring is yfilled in so as to present really a recessed plate .carrying a tubular threaded member I9 whichmaybe screwed on to a. stand or any .other desired piece-of furniture. Y'The ring I6 is-also formed as a recessed plateand, consef quently, there is provided a chamber 20 in which the body of the switch 2| is mounted. The thumb member 22 of the switch extends through the plate I8 so that the switch may be turned on and off as desired. Lead-in wires 23 and 24 extend to the tubular member VI9 and to the switch 2I and to the base of the socket 25. One wire naturally extends to the casing 26 of the socket and the other to the switch 2l so as to provide a proper circuit for the bulb 28. The bulb 28 is elongated and tubular as illustrated in Figure 2. When in use the bulb 28 is screwed into the socket 25 and may be unscrewed at any time. It will be evident that the current may be turned on and off by actuating the switch 2|.

A protecting sleeve or rim 29 has .its lower end embedded in the annular ring I5 and its upper end embedded in the ring 4. This not only protects the socket 25 and associated parts but presents a nice appearance to the lower part of the lamp structure. It will also be noted that the lower end of the threaded rods I4 are provided with caps 30 and that the upper part of the ring 4 is provided with an annular rabbet or groove 3| in which the flange 32 of a ring 33 extends. The ring 33 is secured in any desired manner to the ring 34 of the shade or reflector I3. This shade or reflector I3 is shown particularly in Figure 6. The ring 34 is at the bottom while ring I2 is at the top and carries the flanged ring Il which fits in the groove I0 of ring 3. A plurality of tubes 35 connect rings I2 and 34 and these tubes are secured to the respective rings by respective threaded rods 36 and 31 as shown in Figure 2. Suitable caps 38 and 39 cover the exposed ends' of these rods. In the drawings three tubes 35 have been shown but a greater or less number could be used without departing from the spirit of the invention.

As shown in Figure 3 an arc-shaped reflecting surface 40 is provided. This surface may be ln one piece or may be made in two or more parts and properly secured in place. Preferably this shade member or reflecting structure is a half circle in cross section so that approximately half of the bulb 28 is covered. By reason of the flanges on rings Il and 33 the shade I3 is rotatably mounted and may be moved around the bulb 28 to any desired positionso as to cause illumination from the bulb to be projected `in the desired direction. If desired, however, the rings I2 and 34 could be fixedly secured to the rings 3 and 4.

The various rings 5, 3, I2 and l5 and their associated means may be made from glass, Gallalith, metal, or other desired material. The tubes and rods are preferably made from metal so that they may clamp the various other parts properly in assembled position.

I claim: l

1. An electric lamp comprising a frame formed with a top ring, a bottom ring, a pair of spaced intermediate rings, all of said rings beingof the saine diameter, a plurality of rods extending through al1 of said rings, means acting on said rods and rings for connecting said rings to said rods, rotatable annular members arranged between the said intermediate rings, a plurality of tubes acting on said annular members for` holding the annular members against said intermediate rings, a bolt extending through said tubes fork clamp-ing said annular members against said tubes for presenting a rotatable reflector frame, means secured to said rotatable frame acting as a. reflector, means coacting with the rst mentioned frame for forming a base, an electric bulb socket arranged in said base, and means for directing current to said socket, said means including a hand-actuated switch projecting below said base.

2. An electric lamp of the character described including a main frame, an auxiliary frame adapted to rotate around said main frame, a reector carried by said auxiliary frame, a base secured to said main frame, an electric socket carried by said base, means including a switch kfor directing lead-in wires to said electric socket,

and means at the end of said frame opposite that carrying the base presenting a housing for loosely receiving the end of the bulb screwed into said electric socket.

3. An electric lamp of the character described including a, main frame formed of a plurality of rods, a pair of spaced ring members adjacent each end of said rods, annular rotatable members arranged adjacent the two inner rings of said pair of rings, a plurality of tubes spacing said annular members and holding the same in operative position, screw members extending through said annular members into said tubes for clamping the annular members rigidly to the tubes, a reflector carried by said annular members and said tubes and a socket arranged in the lower part of said frame, and means for directing lead-in wires to said socket.
